Description

Technical Field

[0001] The utility model relates to the technical field of building protection, in particular to an anti-dumping green building steel frame structure. Background Art

[0002] Steel-frame mobile toilets not only demonstrate the flexibility and efficiency of modern construction technology but also embody the concept of sustainable green architecture. Their design fully incorporates the principles of environmental protection and resource reuse, effectively minimizing environmental impact through the use of recyclable materials and the reduction of construction waste. Furthermore, their modularity and portability allow them to be quickly deployed and disassembled in different locations, further reducing energy consumption during construction and transportation. Therefore, steel-frame mobile toilets not only meet the needs of temporary or mobile populations, but also minimize environmental impact.

[0003] In the prior art, in mobile toilets with steel frame structures, since heavier components such as water tanks or solar panels are usually placed on the top, the center of gravity is relatively high. The higher center of gravity makes the structure more susceptible to lateral wind forces, especially in open outdoor environments. Strong winds can produce a large overturning moment, resulting in structural instability. Secondly, the layout of the internal facilities of the mobile toilet also has a significant impact on stability. Usually, a washbasin is installed on one side of the toilet, which causes the center of gravity on that side to be higher. In addition, the design of mobile toilets usually has a larger left and right area and a smaller front area. Although this design is conducive to saving space and providing a larger usable area, when subjected to strong winds, the larger side area will bear more wind pressure, thereby increasing the risk of tipping over to the sides. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an anti-dumping green building steel frame structure.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: an anti-dumping green building steel frame structure, comprising a movable steel frame toilet body and an installation base, both sides of the installation base are provided with a top rectangular groove, the bottom of the top rectangular groove is provided with a rectangular slide groove, the inner wall of the rectangular slide groove is slidably connected to a pedestal, one end of the pedestal is fixed with an inclined surface member, the top of the pedestal is fixed with a square slide member, the side surface of the square slide member is slidably connected to the inner wall of the top rectangular groove, the inner wall of the square slide member is provided with a winding mechanism, the winding mechanism is provided with an auxiliary belt, the inner wall of the top rectangular groove is rotatably connected to a pulley, the surface of the pulley is provided with an auxiliary belt, and one end of the auxiliary belt is fixed There is a hanging ring, the circumference of which is rotatably connected to the side of the movable steel frame toilet body. In the prior art, in the mobile toilet with a steel frame structure, since heavy components such as water tanks or solar panels are usually placed on the top, the center of gravity is relatively high. The higher center of gravity makes the structure more susceptible to lateral wind force, especially in an open outdoor environment. The action of strong wind will produce a large overturning moment, resulting in structural instability. Secondly, the layout of the internal facilities of the mobile toilet also has a significant impact on stability. Usually, a wash basin will be installed on one side of the toilet, which will cause the center of gravity of that side to be higher. In addition, the design of the mobile toilet is generally It often has a larger left and right area and a smaller front area. Although this design is conducive to saving space and providing a larger usable area, when it is subjected to strong winds, the larger side area will bear more wind pressure, thereby increasing the risk of tipping over to both sides. In response to such problems, the utility model adopts the method of installing auxiliary belts to solve it. When the staff is installing it, the movable steel frame toilet body is placed on the supporting platform and the installation base. When the wind pressure on one side is greater, the movable steel frame toilet body has a tendency to tip over to the other side. The change in the tipping angle causes the hanging ring on one side to pull the auxiliary belt, and the auxiliary belt changes the direction of the force through the pulley, so that the auxiliary belt Pull the square slide piece in the top moment groove toward one end of the pulley, and the pedestal and the inclined piece will move accordingly and gradually be retracted into the moment groove. When the wind pressure on one side of the movable steel frame bathroom body is greater and the pedestal at the bottom is retracted into the moment groove, the bottom of the movable steel frame bathroom body at this location will quickly drop like a cliff, causing the tilted movable steel frame bathroom body to be quickly corrected due to the lowering of the base. At the same time, due to the presence of the inclined piece, the base height can be continuously adjusted according to the different tilting angles, so that the movable steel frame bathroom body can be continuously adjusted within a larger tilting angle range, thereby maintaining stability, thereby achieving the effect of improving the anti-tilting ability of the equipment and improving the stability of the equipment.

[0006] Preferably, the belt winding mechanism includes a winding shaft, both ends of the winding shaft are fixed to the inner wall of the square slide, a spiral spring is fixed on the circumference of the winding shaft, and a shielding disk is rotatably connected to the circumference of the winding shaft, a winding ring is fixed on one side of the shielding disk, and a belt outlet hole is opened in a circumferential array on the circumference of the winding ring, and one end of the spiral spring is fixed to the other end of the auxiliary belt. In the prior art, when the wind pressure on one side is large, the tilting of the movable steel frame bathroom body will cause the distance between the hanging ring on the auxiliary belt on the other side and the mounting base to gradually shorten. Since the length of the auxiliary belt is fixed, when the hanging ring is close to the base, the tension of the auxiliary belt will decrease, thereby losing the tight state, which is very important for maintaining the tight state of the auxiliary belt. Maintaining the stability of the entire structure is crucial. Once the auxiliary belt begins to loosen, its coordination with the pulley will be affected. Under normal circumstances, the auxiliary belt should fit tightly on the pulley to ensure effective force transmission and structural stability. However, once the auxiliary belt loosens, it will slide off or detach from the pulley, which will cause the coordination between components to fail. To solve this problem, the utility model adopts the method of installing a vortex spring to solve it. When the distance between the hanging ring and the mounting base gradually shortens, the vortex spring releases its elastic potential energy, so that the vortex spring drives the shielding disk and the winding ring to tighten and rotate, and the auxiliary belt is tightly bound to the winding ring to prevent it from detaching from the pulley, thereby achieving the effect of improving the stability of the equipment.

[0007] Preferably, trapezoidal grooves are provided on both sides of the inner wall of the top rectangular groove, and the inner wall of the trapezoidal groove is slidably connected with a side right-angle piece, and one side of the side right-angle piece is fixed to the side of the square slide. In the prior art, due to the different positions of the square slide on the inner wall of the top rectangular groove, the angles between it and the pulley are also different, which easily causes the square slide to tilt and flip, greatly increasing the friction between the component and the groove, resulting in serious wear between the components and reduced service life of the equipment. To solve such problems, the utility model adopts the method of installing side right-angle pieces to achieve a solution, and realizes the combination of multiple side right-angle pieces and the square slide, and its balanced sliding in the trapezoidal groove, so that the square slide cannot flip in the top rectangular groove and can only rotate in the established track, so that wear is greatly reduced, thereby achieving the effect of increasing the service life of the equipment.

[0008] Preferably, a resisting elliptical pad is fixed on the inclined surface of the inner wall of the mounting base to prevent the movable steel frame bathroom body from rotating too much to the other side when the wind pressure on one side is greater, thereby reducing the impact of wind pressure on the equipment and improving the stability of the equipment.

[0009] Preferably, a stabilizing triangle is fixed to the side of the mounting base to improve the stability of the equipment.

[0010] Preferably, a thin blocking ring is fixed on the circumferential surface of the winding ring to limit the position of the auxiliary belt on the circumferential surface of the winding ring, prevent it from shifting, and improve the operation stability of the equipment.

[0011] Preferably, the surface of the shielding disk is provided with weight-reducing holes to reduce its own weight and improve the sensitivity of the equipment.

[0012] Beneficial effects:

[0013] 1. In the prior art, in mobile toilets with steel frame structures, since heavier components such as water tanks or solar panels are usually placed on the top, the center of gravity is relatively high. The higher center of gravity makes the structure more susceptible to lateral wind force, especially in open outdoor environments. Strong winds will produce a large overturning moment, resulting in structural instability. Secondly, the layout of the internal facilities of the mobile toilet also has a significant impact on stability. Usually, a washbasin is installed on one side of the toilet, which will cause the center of gravity on that side to be higher. In addition, the design of mobile toilets usually has a larger left and right area and a smaller front area. Although this design is conducive to saving space and providing a larger usable area, when subjected to strong winds, the larger side area will bear more wind pressure, thereby increasing the risk of tipping over to the sides. In response to such problems, the utility model adopts the method of installing auxiliary belts to solve the problem, which is realized when the staff installs At the same time, due to the presence of the inclined plane, the base height can be continuously adjusted according to the different tilting angles, so that the movable steel frame bathroom body can always be adjusted in a larger tilting angle range, thereby maintaining stability, thereby improving the anti-tilting ability of the equipment and improving the stability of the equipment.

[0014] 2. In the prior art, when the wind pressure on one side is greater, the tilting of the movable steel frame toilet body will cause the distance between the hanging ring on the auxiliary belt on the other side and the mounting base to gradually shorten. Since the length of the auxiliary belt is fixed, when the hanging ring is close to the base, the tension of the auxiliary belt will decrease, thereby losing its tight state. The tight state of the auxiliary belt is crucial to maintaining the stability of the entire structure. Once the auxiliary belt begins to relax, its coordination with the pulley will be affected. Under normal circumstances, the auxiliary belt should fit tightly on the pulley to ensure effective force transmission and structural stability. However, once the auxiliary belt relaxes, it will slide off or detach from the pulley, which will cause the coordination between the components to fail. To solve this problem, the present invention solves it by installing a vortex spring. When the distance between the hanging ring and the mounting base gradually shortens, the vortex spring releases its elastic potential energy, so that the vortex spring drives the shielding disk and the winding ring to tighten and rotate, tightly binding the auxiliary belt to the winding ring to prevent it from detaching from the pulley, thereby improving the stability of the equipment.

[0015] 3. In the prior art, due to the different positions of the square sliders on the inner wall of the top moment groove, the angles between the sliders and the pulleys are also different, which can easily cause the square sliders to tilt and flip, greatly increasing the friction between the components and the groove, resulting in serious wear between the components and a reduced service life of the equipment. To address this problem, the present invention solves it by installing right-angled side pieces, and realizes the combination of multiple right-angled side pieces and square sliders, as well as their balanced sliding in the trapezoidal groove, so that the square sliders cannot flip in the top moment groove and can only rotate in a predetermined track, which greatly reduces wear and tear, thereby achieving the effect of increasing the service life of the equipment.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0025] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

[0027] Reference Figure 1-6, an anti-dumping green building steel frame structure, including a movable steel frame toilet body 1 and an installation base 101, top rectangular grooves 201 are opened on both sides of the installation base 101, and a rectangular slide 2 is opened at the bottom of the top rectangular groove 201, and the inner wall of the rectangular slide 2 is slidably connected with a base 203, and an inclined surface member 202 is fixed at one end of the base 203. A square slide 204 is fixed on the top of the base 203, and the side of the square slide 204 is slidably connected to the inner wall of the top rectangular groove 201. A winding mechanism is provided on the inner wall of the square slide 204, and the winding mechanism is provided with an auxiliary belt 207. The inner wall of the top rectangular groove 201 is rotatably connected with a pulley 206, and an auxiliary belt 207 is provided on the surface of the pulley 206. One end of the auxiliary belt 207 is fixed The hanging ring 208 is rotatably connected to the side of the movable steel frame toilet body 1. In a mobile toilet with a steel frame structure, since heavy components such as water tanks or solar panels are usually placed on the top, the center of gravity is relatively high. The higher center of gravity makes the structure more susceptible to lateral wind force, especially in an open outdoor environment. The action of strong wind will produce a large overturning moment, resulting in structural instability. Secondly, the layout of the internal facilities of the mobile toilet also has a significant impact on stability. Usually, a washbasin will be installed on one side of the toilet, which will cause the center of gravity on that side to be higher. In addition, the design of the mobile toilet usually has a larger left and right area and a smaller front area. Although this design is conducive to saving space and providing a larger usable area, when subjected to strong winds, the larger side area will bear more wind pressure, thereby increasing the risk of tipping over to both sides. The problem is solved by installing auxiliary belts 207. When the staff is installing, the movable steel frame toilet body 1 is placed on the support platform 203 and the installation base 101. When the wind pressure on one side is greater, the movable steel frame toilet body 1 tends to tip over to the other side. The change in the tipping angle causes the hanging ring 208 on one side to pull the auxiliary belt 207. The auxiliary belt 207 changes the direction of the force through the pulley 206, so that the auxiliary belt 207 pulls the square slide 204 in the top moment groove 20 1 approaches one end of the pulley 206, and the pedestal 203 and the inclined surface member 202 move accordingly and gradually retract into the moment slide 2. When the pedestal 203 at the bottom of one side of the movable steel frame bathroom body 1 with greater wind pressure retracts into the moment slide 2, the bottom of the movable steel frame bathroom body 1 at this location quickly drops like a cliff, so that the tilted movable steel frame bathroom body 1 is quickly corrected due to the lowering of the base. At the same time, due to the presence of the inclined surface member 202, the base height can be continuously adjusted according to the different tilting angles, so that the movable steel frame bathroom body 1 can be continuously adjusted in a larger tilting angle range, thereby maintaining stability, thereby improving the anti-tilting ability of the equipment and improving the stability of the equipment.The belt winding mechanism includes a winding shaft 3, both ends of which are fixed to the inner wall of the square slider 204, a spiral spring 301 is fixed to the circumference of the winding shaft 3, and a shielding disk 302 is rotatably connected to the circumference of the winding shaft 3, a winding ring 205 is fixed to one side of the shielding disk 302, and a circular array of belt outlet holes are opened on the circumference of the winding ring 205. One end of the spiral spring 301 is fixed to the other end of the auxiliary belt 207. When the wind pressure on one side is large, the tipping of the movable steel frame bathroom body 1 will cause the distance between the hanging ring 208 on the auxiliary belt 207 on the other side and the mounting base 101 to gradually shorten. Since the length of the auxiliary belt 207 is fixed, when the hanging ring 208 is close to the base, the tension of the auxiliary belt 207 will decrease, thereby losing the tight state. The tight state of the auxiliary belt 207 is very important for maintaining the entire structure The stability of the auxiliary belt 207 is crucial. Once the auxiliary belt 207 begins to relax, its cooperation with the pulley 206 will be affected. Under normal circumstances, the auxiliary belt 207 should fit tightly on the pulley 206 to ensure effective force transmission and structural stability. However, once the auxiliary belt 207 is relaxed, it will slide off or detach from the pulley 206, which will cause the cooperation between the components to fail. This is solved by installing a vortex spring 301. When the distance between the hanging ring 208 and the mounting base 101 gradually shortens, the vortex spring 301 releases its elastic potential energy, so that the vortex spring 301 drives the baffle plate 302 and the winding ring 205 to tighten and rotate, and the auxiliary belt 207 is tightly bound to the winding ring 205 to prevent it from detaching from the pulley 206, thereby improving the stability of the equipment.

[0028] The top groove 201 has trapezoidal grooves 401 on both sides of the inner wall, and the inner wall of the trapezoidal groove 401 is slidably connected with a side right-angle piece 4. One side of the side right-angle piece 4 is fixed to the side of the square slide 204. Due to the different position of the side right-angle piece 4 and the square slide 204 on the inner wall of the top groove 201, the angle between the side right-angle piece 4 and the pulley 206 is also different, which easily causes the square slide 204 to tilt and flip, greatly increasing the friction between the components and the groove, causing serious wear between the components and reducing the service life of the equipment. The solution is to install the side right-angle piece 4. Through the combination of multiple side right-angle pieces 4 and the square slide 204, and the balanced sliding of the side right-angle piece 4 in the trapezoidal groove 401, the square slide 204 cannot flip in the top groove 201 and can only rotate in the predetermined track, which greatly reduces wear and tear and achieves the effect of improving the service life of the equipment. The inner wall inclined surface of the mounting base 101 is fixed with a friction elliptical pad 5 to prevent the movable steel frame bathroom body 1 from rotating greatly to the other side when the wind pressure on one side is large, reducing the impact of wind pressure on the equipment and improving the stability of the equipment. A stabilizing triangle 501 is fixed to the side of the mounting base 101 to enhance the stability of the device. A thin retaining ring 303 is fixed to the periphery of the winding ring 205 to limit the position of the auxiliary belt 207 on the winding ring 205, preventing it from shifting and improving the stability of the device. Lightening holes are opened on the surface of the shielding plate 302 to reduce its own weight and improve the sensitivity of the device.

[0029] The working principle of the present invention is as follows: when the staff is installing, the movable steel frame toilet body 1 is placed on the support 203 and the installation base 101. When the wind pressure on one side is greater, the movable steel frame toilet body 1 tends to tilt to the other side. The change in the tilting angle causes the hanging ring 208 on one side to pull the auxiliary belt 207. The auxiliary belt 207 changes the direction of the force through the pulley 206, so that the auxiliary belt 207 pulls the square slide 204 in the top moment groove 201 to approach one end of the pulley 206. The support 203 and the inclined member 202 follow the direction of the force. The movable steel frame toilet body 1 is moved along the vertical axis and gradually enters the moment slide 2. When the bearing platform 203 at the bottom of the movable steel frame toilet body 1 on one side of the movable steel frame toilet body 1 with greater wind pressure enters the moment slide 2, the bottom of the movable steel frame toilet body 1 at this location quickly falls like a cliff, so that the tilted movable steel frame toilet body 1 is quickly corrected due to the lowering of the base. At the same time, due to the presence of the inclined member 202, the base height can be continuously adjusted according to the different tilting angles, so that the movable steel frame toilet body 1 can be continuously adjusted in a larger tilting angle range, thereby maintaining stability.
